   URGENT - IMMEDIATE BROADCAST REQUESTED
   Tornado Watch Number 518
   NWS Storm Prediction Center Norman OK
   220 PM EST Thu Dec 24 2020

   The NWS Storm Prediction Center has issued a

   * Tornado Watch for portions of 
     Central and Eastern North Carolina
     Eastern South Carolina
     Coastal Waters

   * Effective this Thursday afternoon and evening from 220 PM until
     1000 PM EST.

   * Primary threats include...
     A few tornadoes likely
     Scattered damaging wind gusts to 70 mph possible

   SUMMARY...The air mass ahead of an eastward-advancing cold front
   will moisten and modestly destabilize this afternoon. Very strong
   winds through a deep layer will support the possibility of supercell
   storms including a tornado and damaging wind risk. An additional
   round of storms, perhaps as a well-organized line, will also move
   into the region from the west late this evening and potentially pose
   a severe threat.

   The tornado watch area is approximately along and 70 statute miles
   east and west of a line from 50 miles east northeast of Rocky Mount
   NC to 20 miles south of Myrtle Beach SC. For a complete depiction of
   the watch see the associated watch outline update (WOUS64 KWNS
   WOU8).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Tornado Watch means conditions are favorable for
   tornadoes and severe thunderstorms in and close to the watch
   area. Persons in these areas should be on the lookout for
   threatening weather conditions and listen for later statements
   and possible warnings.

   &&

   AVIATION...Tornadoes and a few severe thunderstorms with hail
   surface and aloft to 1 inch. Extreme turbulence and surface wind
   gusts to 60 knots. A few cumulonimbi with maximum tops to 400. Mean
   storm motion vector 22045.

Please visit the National Weather Service Interactive Weather Information Network (IWIN) for more information on the warnings.

For each watch, probabilities for particular events inside the watch (listed above in each table) are determined by the issuing forecaster. The "Low" category contains probability values ranging from less than 2% to 20% (EF2-EF5 tornadoes), less than 5% to 20% (all other probabilities), "Moderate" from 30% to 60%, and "High" from 70% to greater than 95%. High values are bolded and lighter in color to provide awareness of an increased threat for a particular event.
